Jordan Raychev, Diyana Kinaneva, Georgi Hristov, Plamen Zahariev · 2019
Switch to multi controller migration is still a hot topic in SDN research field which requires a lot of factors to be considered. Among those factors is SDN controller scalability, migration stability and load balancing rate across all controllers. The focus of the paper is to present a new approach for optimizing SDN control plane scalability and controllers load balancing rate through efficient switch to controller migration by using self-balancing binary search trees.
